"I long ago realized that I could reach far more people by writing something, than by walking down the street with a banner."

| Atmosphere Tester | ||
| A device used to test the composition of a sample of the atmosphere on another planet, to see if it is breathable by humans. |
When Al and Joe arrive on a planet in an unknown universe, they would like to take off their uncomfortable space suits. But will the atmosphere sustain human life?
| "How about removing our space suits? I always feel uncomfortable in them," Al continued.
"Just a moment while I test this atmosphere to see if it's livable." Joe extracted from the pocket of his suit a clever little device. The turn of a valve, the pressure of a button, and an electric coil heated a sample of the atmosphere. A glance through the tiny spectroscope attachment, and its constitution was revealed. "Oxygen, nitrogen, carbon dioxide - the same gases that make up our air And just about in the same proportions. Alright Al, we can breathe this atmosphere. Off go the suits!" |

Very practical device; this is an early reference to the idea, as far as I know.
